This study aimed to examine the relationships between presumed water availability for acacia populations and their mortality by examining the effect on tree mortality of latitude, basin size, and microhabitat in the valley floor. A total of 1 980 acacia trees in 11 wadis along the Arava and eastern Negev region were studied. The obtained results revealed a highly varied inter-wadi mortality rate. A negative correlation was revealed between latitude and tree mortality rate. No correlation was revealed between basin area and tree mortality rate. Various rates of tree mortality were observed in different microhabitats. The low occurrence of small tree-size group indicates low rate of recruitmen
